Abstract

Disclosed is a filter comprised of activated carbon fibers, wherein said filter has a Virus Removal Index (hereafter 'VRI') of at least about 99 %, as measured in accordance with the test method described in the specification. The filter may comprise unbound fibers, or the fibers may be bound with a binder to form a composite of fibers. Also disclosed is a method of removing viruses from a liquid, the method comprising contacting the liquid with a filter comprising activated carbon fibers wherein said filter has a VRI of at least about 99 %. Also described is an article of manufacture comprising: (a) a filter comprising activated carbon fibers, wherein said filter has a VRI of at least about 99 %; and (b) instructions which inform a user that the filter may be used to remove viruses from a liquid.
